A panel of 81 Asian, African and European cattle (Bos taurus and B. indicus) was sequenced for the exon 9 of the ARHGAP15, a strong candidate for cattle trypanotolerance on BTA2. The analyses provided five different haplotypes defined by four (two nonsynonymous) mutations. Neutrality tests suggest a recent sweep in the studied bovine sequences. The two most frequent haplotypes (H1 and H3) gathered 88% of the chromosomes analyzed and were present in all the cattle groups analyzed, including Asian zebu and European cattle. The current results question the sole association of the polymorphism identified, including mutation c.53317501A>C, with the trypanotolerant response in West African cattle.
